Abstract:
Shaped containers fabricated from material comprising biodegradable thermoplastic oxyalkanoyl polymers, e.g., epsiloncaprolactone polymers, said containers possessing a medium to germinate and grow seed or seedling, and optionally, a seed or seedling in such medium.
Abstract:
Shaped articles fabricated from material comprising particulate addition polymer, e.g., polyethylene, in a matrix of biodegradable thermoplastic oxyalkanoyl polymer, e.g., epsiloncaprolactone homopolymer. Such articles are useful as mulch film, transplanter containers, package containers, and the like.
Abstract:
Biodegradable-environmentally degradable transplanter containers are formed from a biodegradable thermoplastic polymer, e.g., poly(epsilon-caprolactone) or poly(ethylene adipate), and an environmentally degradable normally-solid ethylene polymer based composition.
Abstract:
Shaped containers fabricated from material comprising biodegradable thermoplastic oxyalkanoyl polymers, e.g., epsiloncaprolactone polymers, and naturally occurring biodegradable product, e.g., fir bark, said containers possessing a germination medium, and optionally, a seed or seedling therein.
Abstract:
Novel polymeric blends which are capable of being fabricated into useful and novel consumer-type and industrial-type plastic products. After the useful life of such products they can be discarded. The ambient surrounding elements, including microorganisms and sunlight, thereafter cause the discarded products to degrade. The novel blends comprise a biodegradable thermoplastic polymer, e.g., poly(epsilon-caprolactone) or poly(ethylene adipate), and an evironmentally degradable normally-solid ethylene polymer.
